The war in front of us is urgent and unlucky. If too many soldiers in the first tier are lost, they will launch another attack after a period of easing, and the attack power will inevitably decline sharply. Gu Yan looked at the soldiers trapped inside in the distance and immediately issued an emergency rescue order to the soldiers in the second tier.

"The second echelon, release the 'dirty electric light' to control the mechanical rat!" Gu Yan stood in the distance and directed the team loudly.

Five warriors wearing red summoned energy steel rings rushed forward immediately, facing the danger of being attacked by mechanical rats, one after another released "dirty lightning".

The red clouds were summoned by the soldiers, and the five clouds quickly gathered together, forming a huge sea of ​​clouds. Purple-red lightning quickly slashed down from inside, limiting all the mechanical rats in the clouds to move.

Taking advantage of the "dirty light" to control the local mechanical rats, most of the soldiers in the first tier evacuated safely, while all the gun soldiers in the third tier concentrated their firepower. Suddenly, countless beams of light shot out from the barrel attacked the most deadly key parts of the mechanical rats. The controlled mechanical rats fell to the ground one after another.

"Disfied electric light" can last for a shorter time, and Gu Yan can only use his best efforts to save more soldiers within the effective time. The purple-red clouds gradually fade away, and the soldiers in the second echelon also have to retreat for a distance, so as to make more reasonable tactical arrangements.

"Gu Yan, it's not okay to fight like this!" Lu Bai said hurriedly.

At this time, Lu Bai was also very anxious when he saw this situation. Gu Yan knew it in his eyes and knew it in his heart. After all, Lu Bai had never smoked a cigarette since the beginning of the battle. After Gu Yan glanced at Lu Bai, he looked at the battlefield in the distance. He ignored Lu Bai because he could not think of a good idea at this time.

Seeing that Gu Yan ignored him, Lu Bai said anxiously: "If according to the Guard Captain's guess, the mechanical rat's defense zone can change its combat plan every ten minutes after being attacked. From the beginning of the attack, it has been almost 5 minutes, and the mechanical rat's defense zone we captured is less than one-third. How can we fight like this? After another 5 minutes, the enemy mechanical rat will change its strategy for the enemy, and we will fall into a passive situation at that time."

"Don't worry, keep changing."

Lu Bai listened to Gu Yan's answer and his face was filled with incredible expressions, "What kind of logic is this? If the enemy mechanical rats make strategic adjustments again, we will have to face a group of new mechanical rats, then what can we do?"

"Now I am the commander, and I will obey my command of all actions. If you have any objections, please leave immediately." Gu Yan looked into the distance, with a cold and serious expression.

Lu Bai around him was indeed in a state at this time. Some of the questions he asked were exactly what Gu Yan was thinking about. Now that he has used all his tactics, the effect of attacking mechanical rats is not as obvious as expected.

Time passed by minute by minute, and Gu Yan also knew that if he had not yet come up with a suitable combat policy within the established time, if the mechanical rats first changed their combat strategy, the next battle against the mechanical rats would undoubtedly be to block the car with the mantis arm.

At this time, a-wing nebula fighter jets flew past in the sky. They circled back and forth in the air one after another, and the overwhelming artillery fire aimed at the defense zone of the mechanical rat, but the effect of killing the mechanical rat was not very obvious.

Gu Yan firmly saw the situation at this time, but he could not change his combat policy. Judging from the current situation, when the mechanical rat did not change its defensive strategy, the only thing he had confidence in at this time was to follow the original tactics step by step.

Now the soldiers in the three echelons have retreated outside the attack range of the mechanical rats. They are all repairing on the spot, using the attack tanks as cover, and cooperating with the nebula fighter jets in the sky to shoot the mechanical rats from a long distance.

"It's changed, it's changed, Gu Yan! Look over there!" Lu Bai kept shouting in Gu Yan's ear.

At this moment, Gu Yan was turning back to communicate with the soldiers behind him. When he heard Lu Bai's shouting, he hurriedly turned around and looked at the mechanical rat defense area in the distance, some abnormal changes did occur again.

"It's not even ten minutes before this, why did the mechanical rat's combat strategy begin to change?" Gu Yan asked casually in confusion.

"Ten minutes are just a rough number, and you don't have to wait until ten minutes." Lu Bai said it thoroughly, and he seemed to be very knowledgeable about this matter.

At this moment, the semi-intelligent man's control over the mechanical rats was also changing rapidly. The mechanical rats in front of him immediately became very active as if they were injected with their souls. They began to walk around from the defense area.

"What exactly makes them change so much? Lu Bai, you heard the instructor explain the mechanical rat, let's talk about it." Gu Yan asked Lu Bai.

"I just listened roughly."

"It's probably good to have one, please share it with everyone soon. Time is not waiting for anyone." Gu Yan said to Lu Bai in a hurry.

Lu Bai pointed to the mechanical rats walking around in the distance and said, "Mechanical rats will always only perform inherent commands. If their behavior suddenly becomes abnormal, then they must have received new tasks. Now the mechanical rats in front of you naturally leave their defense areas, so this means we have to be careful."

As soon as Lu Bai finished speaking, he could only hear abnormal movements in the distance. He saw dust flying over the sand in the distance. Hundreds of mechanical rats were rushing towards Gu Yan's defense zone with the firepower of the Nebula fighter jets.

In the human defense area in front of us, there was a lifeless scene. Most of the recruits were frightened by the momentum of the mechanical rat. Most of them only dared to hide behind the attacking car, and they didn't even have the courage to take out the atomic beam gun.

"It's really changed. What should Gu Yan do now?" Lu Bai asked.

"What else can I do? Everyone's energy steel ring skills have not been restored. For the time being, they can only use the attack car as a cover."

Seeing that Gu Yan had no good suggestions, Lu Bai expressed his thoughts, "Not everyone's energy ring has not recovered. Your energy ring and I have not opened yet. Otherwise, how about the two of us join forces together?"

Listening to Lu Bai's inspiring words, Gu Yan felt a ball of passionate blood flowing in an instant. He immediately stretched out his palm, and after they clapped the high fives, they rushed towards the direction of the mechanical rat attack.

Hahahaha. A boring smile.

So boring.
